Background:
The quality of one's facial appearance diminishes with aging as skin and underlying soft tissues deteriorate. Connective tissue and musculofascial degeneration leads to skin laxity and wrinkles developing.
Objective:
To evaluate the effects of synchronized radiofrequency with high intensity facial stimulation technology on dermal collagen and elastin fibers in a porcine model.
Materials And Methods:
Eight sows were divided into Active (N = 6) and Control (N = 2) groups. Synchronized radiofrequency and high intensity facial stimulation were delivered to the ventrolateral abdomen. The Active group received four 20-minute treatments, once a week. Control group was untreated. Skin biopsy sample were histologically analyzed for connective tissue changes pre- and post-treatment. Data were analyzed statistically (α = 0.05).
Results:
In the Active group: the collagen-occupied area at baseline was 1.12 ± 0.09 × 106 μm 2 and increased by +19.6% ( p < .001) at 1-month and by +26.3% ( p < .001) 2 months post-treatment; elastin-occupied area at baseline was 0.11 ± 0.03 × 106 μm 2 and increased by +75.9% ( p < .001) at 1-month and +110.8% ( p < .001) at 2-months follow-up. No significant changes ( p > .05) found in the Control samples.
Conclusion:
Collagen and elastin fiber content increased significantly after treatments. Connective tissue in the treatment area was denser up to 2-months post-treatment.
